Drama is a stage performing art in which actors play characters and perform on to achieve narrative purposes the form of speech, movement, dance so on. The literary concept drama refers script, or play, written for theatrical performance. Translation theorist Susan Basnett has accordingly proposed famous principle performability, provides new perspective study translation. This paper examines d...

Abstract Action theory may be regarded as a theoretical foundation of AI, because it provides in logically coherent way the principles performing actions by agents. But, more importantly, action offers formal ontology mainly based on set-theoretic constructs. This isolates various types structured entities: atomic, sequential, compound, ordered, situational etc., and is solid non-removable any ...

We propose a two-phase methodology for quantifying the performability (performance + availability) of cluster-based Internet services. In the first phase, evaluators use a fault-injection infrastructure to measure the impact of faults on the server’s performance. In the second phase, evaluators use an analytical model to combine an expected fault load with measurements from the first phase to a...

Quality attributes, such as performance and dependability of a software-intensive system are constrained by its software architecture. The combined performance and dependability (called performability) effects of an architecture can be evaluated by constructing a performability model that considers the failure/repair behavior and performance attributes of its components, interactions among the ...

Haverkort, B.R., Approximate performability and dependability analysis using generalized stochastic Petri nets, Performance Evaluation 18 (1993) 61-78. Since current day fault-tolerant and distributed computer and communicat ion systems tend to be large and complex, their corresponding performability models will suffer from the same characteristics. Therefore, calculating performability measure...

Performability measures are often defined for analyzing the worth of fault-tolerant systems whose performance is gracefully degradable. Accordingly, performability evaluation is inherently well-suited for application of reward model solution techniques. On the other hand, the complexity of performability evaluation for solving engineering problems may prevent us from utilizing those techniques ...

Abstract A methodology for performance assessment of prestressed concrete (PSC) girder bridge system, based on strain monitoring in limited number girders, is proposed this paper. The uses Polya urn model determining probabilities the system being different condition states with respect to loss prestress. Performability measure used describing system. state assigned from a predefined set states...

In this paper we discuss a unified approach towards model-based quantitative evaluation of both computer systems and communication systems. In the area of fault-tolerant computer systems, dependability evaluation has been recognized as being a topic of importance, both to judge a system on its merits and to provide trust in the actual dependability of the system. In communication systems, the n...

Stochastic methods are commonly used for dependability evaluation. In the mid 1970’s, stochastic evaluation was proposed for combined performance/dependability evaluation, called performability evaluation. Extending reliability evaluation to include performance related behaviors presented new challenges, most notably due to the large difference in time scale of performanceand dependability-rela...
